+<p align="center">
+    Initialize your program with Setup
+</p>
+
+When a program needs to do some init work at startup—like parsing global args or registering resources—you can organize that logic with `#[program_setup]`.
+
+## Initialize with Setup
+
+```rust
+// Features: ["extra_macros"]
+@@@use mingling::macros::program_setup;
+@@@use mingling::Program;
+#[program_setup]
+fn my_setup(program: &mut Program<ThisProgram>) {
+    // Extract global flag from args
+    program.global_flag(["-v", "--verbose"], |program| {
+        program.stdout_setting.verbose = true;
+    });
+}
+@@@
+@@@fn main() {
+@@@    let mut program = ThisProgram::new();
+@@@    program.with_setup(MySetup);
+@@@    program.exec_and_exit();
+@@@}
+@@@gen_program!();
+```
+ 
+A function annotated with `#[program_setup]` receives `&mut Program<ThisProgram>`, where you can do any init work.
+
+Register it in `main` via `program.with_setup(...)` to use it.
+
+> [!NOTE]
+> `#[program_setup]` requires the `extra_macros` feature. Without it, you can manually implement the `ProgramSetup` trait.
+
+## Extract Global Args
+
+The most common use of Setup is extracting global args. Mingling provides a few helper methods:
+
+```rust
+// Features: ["extra_macros"]
+@@@use mingling::macros::program_setup;
+@@@use mingling::Program;
+#[program_setup]
+fn my_setup(program: &mut Program<ThisProgram>) {
+    // Boolean flag
+    program.global_flag(["-v", "--verbose"], |program| {
+        program.stdout_setting.verbose = true;
+    });
+ 
+    // Flag with a value
+    program.global_argument("--name", |_program, value| {
+        // value is "Alice"
+        let _ = value;
+    });
+}
+```
+ 
+> [!TIP]
+> `global_flag` and `global_argument` automatically remove matched args from `program.args`, so they won't enter the pipeline.
+
+## Built-in Setup
+
+Mingling provides several ready-to-use Setups covering the most common CLI program needs:
+
+| Setup                       | Functionality                                                                              |
+| --------------------------- | ------------------------------------------------------------------------------------------ |
+| `BasicProgramSetup`         | Parses `--help`/`-h`, `--quiet`/`-q`, `--confirm`/`-C`                                     |
+| `DirectoryEnvironmentSetup` | Registers directory resources: current dir, executable dir, home dir, temp dir             |
+| `ExitCodeSetup`             | Controls program exit code via `ResExitCode`                                               |
+| `StructuralRendererSetup`   | Enables `--json`, `--yaml` etc. structured output (requires `structural_renderer` feature) |
+
+Usage is just one line in `main`:
+
+```rust
+@@@use mingling::setup::BasicProgramSetup;
+fn main() {
+    let mut program = ThisProgram::new();
+    program.with_setup(BasicProgramSetup);
+    program.exec_and_exit();
+}
+```
+ 
+`BasicProgramSetup` handles common params that most CLI programs need, saving you the trouble of manual parsing.
